Magicboost works in a pretty simple way. The extra magic is only available for casting. It won't increase cost of paths or count for bless and you don't even see it while picking the pretender.

I would also note that the #magicskill stuff on the second shape is pointless as it will inherit any magic from the primary shape anyway. However there is no real loss from having them either. #startdom, #pathcost and #restrictedgod on the second shape will also probably result in the nation also having access to a pretender chassis named "Oni Spirit" which I don't think is the goal. You should be able to safely remove all of them.
